Description

Optical connector with fulcrum for optical alignment

This application relates to optical connectors, and specifically to optical connectors with pivot points for optical alignment.

As data rates in computers continue to rise, copper conductors become increasingly unable to carry large amounts of high-speed data between components at the speeds consumers demand. Silicon photonics (that is, systems that use silicon as the optical medium to transmit data) help alleviate this bottleneck by enabling data to be transmitted through optical fibers instead of copper traces. Achieving efficient coupling of light between optical fibers and small-core photonic integrated circuit (PIC) waveguides can be challenging. Existing solutions involve active alignment and permanent attachment of optical fibers, which are expensive, slow, very lossy, and incompatible with the temperatures associated with solder reflow of PICs.

Some silicon photonics systems already use pluggable connector interfaces between fiber optics and silicon photonics transceivers, including optical brackets that are bonded to the PIC and optical sockets that are seated into the optical bracket and maintained in optical alignment with the transceivers. . While this pluggable interface provides improvements in the process of obtaining optical alignment, it can still be challenging to align the lenses built into some optical carriers with the grating couplers on the PIC. The carrier lens must be laterally aligned with its respective grating coupler for optical data transmission. However, differences in manufacturing procedures can This results in significant cross-wafer and wafer-to-wafer variation in the angle of the output beam from the grating coupler, so the carriage must be actively angularly aligned to focus the light into (or out of) the grating coupler. , while keeping the grating coupler at or near the focus of the respective carrier lens.
